Unique Click

What is Unique Click?

A unique click is an affiliate link click counted only once per visitor per session — deduplicated to remove multiple clicks from the same browser session — as distinct from total clicks which count every click event regardless of repetition.

Unique Click In Practice

Unique clicks are the more meaningful metric for affiliate performance analysis because they represent the number of distinct visitors sent to a merchant, not the number of click events. A single visitor who clicks your affiliate link three times during one browsing session — clicking, navigating back, and clicking again — counts as three total clicks but one unique click. Using total clicks as the denominator in conversion rate calculation artificially deflates the rate: if 10 conversions are achieved from 500 total clicks (many of which are repeat clicks from the same visitors), the true conversion rate from unique visitors is higher than the total-click calculation suggests. Most affiliate network dashboards display both metrics; the standard conversion rate formula uses unique clicks. EPC calculated on unique clicks (commissions divided by unique clicks) is the correct per-visitor income figure because it reflects the actual number of different people sent to the merchant — not the number of times links were clicked. When two programs show the same total commission for the month, the one that achieved it with fewer unique clicks has the higher EPC and is the stronger program per visitor sent.
